This study demonstrates the occurrence of 940 organic micro-pollutants in surface water of four rivers, one irrigation canal system, and two lakes in Vojvodina Province, the northern part of Serbia, summing in total eighteen samples. The number of detected chemicals ranged from 22 to 84, with 127 micro-pollutants detected at least once, representing 13% of the studied substances. The targeted compounds include n-alkanes, sterols, polycyclic aromatic hydrocarbons (PAHs), organochlorine pesticides polychlorinated biphenyls, pesticides, pharmaceutical active compounds, industrial chemicals, plasticizers, etc. Among the analysed compounds, sterols were the most dominant with maximum quantified concentrations. The substances which were quantified with frequency over 50% were two PAHs (2-methylnaphthalene, benzo(ghi)perylene), five sterols (cholesterol, cholestanol, stigmasterol, fucosterol, beta-sitosterol), three pharmaceuticals and personal care products (L-menthol, diethyltoluamide, caffeine), and ten household chemicals (4-tert-octylphenol, dimethyl phthalate, methyl palmitate, phenylethyl alcohol, 1-nonanol, alpha-terpineol, 2-phenoxy-ethanol, methyl myristate, acetophenone, and 2-ethyl-1-hexanol). The list of priority substances under the European Union Directive 2013/39/EU includes 49 priority substances (PSs) out of which 34 were analysed. Among these, eleven PSs were quantified, and only two compounds (fluoranthene and benzo (a) pyrene) exceeded EU Environmental Quality Standards targeted values. The obtained results were compared with the previously published data that dealt with the same targeted number of micro-pollutants in sediment samples. This revealed connections between the same sampling locations. Environmental risk assessment showed the existence of potential ecological risk as 72% of the obtained values for the ecological hazard index (HI) at investigated locations were higher that the targeted value (HI > 1). Estimated values for hazard quotient (HQ) and hazard index (HI) for non-carcinogenic risk were lower than the targeted value, indicating no non-carcinogenic risk through dermal contact and non-intentional ingestion of water. Estimated values for cancer risk were all below 1 × 10⁻⁶, which is not considered to pose significant human health risk.

这项研究表明塞尔维亚北部的伏伊伏丁那省的4条河流，1条灌溉渠系统和2个湖泊的地表水中存在940种有机微污染物，总共有18个样品。被检出的化学物数量在22至84种之间，其中至少有127种微污染物被检出一次，占所研究物质的13％。目标化合物包括正构烷烃，固醇，多环芳烃（PAH），有机氯农药，多氯联苯，农药，药物活性化合物，工业化学品，增塑剂等。在分析的化合物中，固醇含量最高，定量浓度最高。频率超过50％的定量物质是两种PAH（2-甲基萘，苯并（ghi）per），五种甾醇（胆固醇，胆固醇，豆甾醇，岩藻糖醇，β-谷甾醇），三种药品和个人护理产品（L-薄荷醇，二乙基甲苯酰胺，咖啡因）和十种家用化学品（4-叔辛基苯酚，邻苯二甲酸二甲酯，棕榈酸甲酯，苯乙醇，1-壬醇，α-松油醇，2-苯氧基乙醇，肉豆蔻酸甲酯，苯乙酮和2-乙基-1-己醇）。根据欧盟指令2013/39 / EU的优先物质清单包括49种优先物质（PS），其中有34种被分析。其中，对11种PS进行了定量，只有两种化合物（荧蒽和苯并（a）））超过了欧盟环境质量标准的目标值。将获得的结果与之前发表的处理沉积物样品中相同数量的微污染物的数据进行了比较。这揭示了相同采样位置之间的联系。环境风险评估表明存在潜在的生态风险，因为在调查地点获得的生态危害指数（HI）值的72％高于目标值（HI> 1）。非致癌风险的危险商（HQ）和危害指数（HI）的估计值低于目标值，表明没有因皮肤接触和非故意摄入水而引起的非致癌风险。癌症风险的估计值均低于1×10 非致癌风险的危险商（HQ）和危害指数（HI）的估计值低于目标值，表明没有因皮肤接触和非故意摄入水而引起的非致癌风险。癌症风险的估计值均低于1×10 非致癌风险的危险商（HQ）和危害指数（HI）的估计值低于目标值，表明没有因皮肤接触和非故意摄入水而引起的非致癌风险。癌症风险的估计值均低于1×10^-6，不被认为对人类健康构成重大风险。
